Is Steam Integration Coming To Xbox?

Microsoft may be preparing a big announcement for tomorrow if a Reddit thread is to be correct.

According to this Reddit thread, the sub-domain “xbox.steampowered.com” has been active for a little less than a year, with lots of activity being tracked on this domain over the last couple of days. This has lead to a discussion on Reddit as to what Microsoft plans to announce during this time tomorrow. To continue with the speculation, Microsoft has announced that they will be holding a gaming press event tomorrow, February 25th, to talk about Windows 10 and Xbox One. Is it a coincidence?

XboxOneUK.com speculates that the game Quantum Break may tie in with this rumor as Microsoft is promoting the cross-buy promotion, where purchasing it on Xbox One also nets you a free copy on Windows 10. Another thing to note is that Killer Instinct: Season 3 and Gears of War: Ultimate Edition, previously Xbox One exclusives are preparing for launch in the PC market next month. Could these titles also have some relevance to this information?

Of course, this is all just rumor and speculation, what are your thoughts regarding the discussion? Do you think Valve and Microsoft will finally be able to shake hands and allow for cross-platform integration?
